1 LOCK. KEEBERh Application. fileioctober 18, 1920. Serial No. 417,856.

This invention relates to a noiseless door lock keeper used particularly in automobiles, trucks, and. other vehicle. doors.

Also it is;of the: greatest advantage. to. the.

above mentioned. trades. Provisions are made for its use'on ocean steamers, launches, motor boats, yachts, housesfor Wherever a keeper with absolute: locking. qualities. is.

required.

One of'the objects of' this: invention is to produce a keeper for the doors. set. forth, which hastwo or. more locking chambers, whereby a twisted door is immediately brought into alignment. 7

A. further object is. to eliminate .therubber or spring bumpers,v used'at present to-take: up the play, required between the keeper on the post and'the bolt of the lock in all looks used at present.

Another object is that the. keeperwhich is. attached to the post entirely surrounds the bolts. of the iock, simultaneously preventing vertical, horizontal: andtraverse motion, thereby preventing; anyrattl'ing,v which can notbe achieved by the. methods-usediat present.

Still another object isthat the. keeper consists. of" several compartments with removablekeeper'blocks made. preferably. offibre or. other suitable. soundless materiall lithe. locking blockswear out. they. can be replaced instantly without any. fitting, bringing; the door. inthe. same. alignment it .had 1 when new.

A; still. further.v object. is, thefalighment block in the: centre; compartment which is also. removable; with. this block. the. alignment, of the. pillar. rabbet line may be. con-. tinued. 7

Other. objects; and advantages will become apparent. as; the specifioation proceeds.

With theaforesaidlohjects. view the. in-. vention consists ofltheirhprovements; novel construction, arrangements and combinations of part s: hereinafter described, define'd the suhj oined... claimsv and illustrated'.' in. the pre ferred.v embodiments; by the. annexed? drawings, wherein like; elements. are; designated by the samerefrence; charactersthroughout;

pillar or post having its edge rabbeted at 13 same.

and 2 is the keeper frame which consists of a plate having a longitudinal flange 2 at one edge and transverse flanges 2 at its ends and provided with transverse partitions 14. This arrangement provides end compartments 4, for the reception of the bolt receiving blocks 3 which are made of a suitable sound deadening material such, for example, as fibrous material, for the purpose of rendering the .collision of the bolts with the blocks noiseless. These blocks are formed with tapered bolt receivin holes 6 and the blocks are beveled at 19 gsee Figure 9) so that the bolt rides easily over the block in closing the'door. The tapered socket 6 in each of the sound deadening blocks 3 has its mouth flaring outwardly as at 15 in Figure 2 in order to remove the sharp corner and enable the locking bolts to more quickly engage the socket. The removal of this sharp edge also reduces the wearing of the engaging bolt by avoiding any cutting of the The blocks 3 are held to the keeper frame by means of screws 7 and screws 8 also pass through the block 3, likewise the keeper frame and enter into the pillar 1 thereby tightening the block in the frame and securing the frame to the pillar. In the central compartment 11 lying between the transverse partitions 14, is encased the alinement block 12 which is held to the keeper frame by means of screws 9 and screws 10 also passing through the alinement block 12, likewise the keeper frame and into the material of the pillar 1 thereby securing the parts to the pillar.

In Figure 7 the keeper frame 2 and removable block 3 are attached .to the pillar 1. 19 represents the inclined sliding surface for the locking plungers.

' In Figure 10 the pillar is shown with the space for the keeper frame cut away.

' In Figure 11 a plain keeper frame without alignment block, as shown in Figures 15, 16, 21, 22 and 23 and 24 is attached to the pillar, therefore the rabbet line is missing.

In Figure 12 a keeper frame as shown in Figures 1, 2, 3 and 4 is attached to the pillar therefore the rabbet line 13 formed by the alignment block 12 is visible.

Figure 13 is a front view of a keeper as shown in Figures 15, 16, 21, 22, 23 and 24. 2 represents the rear line'of the keeper. 6

the plunger engagement holes, 1 the pillar, 13 the rabbet line.

Figure 14 is a front view of a keeper frame as shown in Figures 1, 2, 3 and 4. 6 represents the taped holes in the removable blocks 3. 1 represents the pillar, 2 the keeper frame attached to the pillar. 12 indicates the removable alignment block shown in Figure 5 also in Figure 19.

As illustrated in Figure 13 with the style of keeper frame used in said figure, the rabbet line 13 is missing for the entire length of the keeper frame.

In Figure 14 with the use of alignment block 12 which is furnished wide enough and quickly removed from and attached again to the said frame. The rabbet line 13 can be quickly continued on the alignment block 12, and the disfigurement of the rabbet line 13 becomes less conspicuous in Figure 14 than in Figure 13.

In Figure 8 the alignment block 12 fills out the full space of the keeper frame opening.

In Figure 12 the same alignment block 12 is cut to correspond with the required rabbet line 13. This illustrates the unlimited adjustment of said alignment block to match rabbet line.

In Figure 9 in the front view of the removable locking block, 6 represents the tapered hole, 7 and 8 indicate holes to fasten it in the openings 4 in the frames shown in Figures 1, 2, 3, 4, 21 and 22. In Figure 9 in the sectional view 6 represents the tapered locking hole, 15 the removed edges, 19 the inclined sliding surface.

In Figures 15, 1e, 17, 1s, 19, 20, 23, 24 and 25 the 6 represents the tapered holes, 15 the removed edges, 19 the inclined sliding surfaces. If the tapered holes 6 or the surface lines 19 become worn in this style of keeper, the entire frame must be renewed. \Vhereas with the keepers shown in Figures 1, 2, 3, 4, 21 and 22 only the block 3 shown in Figure 9 needs renewal.

In Figures 21and 22 16 represent openings for resilient expanding members 17, the latter extending over the edge of the keeper frame. This st le keeper having only one looking point, tie expanding blocks 17 are forcing the door in alignment with the pillar. 18 represents tapered pins to hold 17 in the opening 16. 4 represents the openin for removable block 3 of Figure 9. Sai block 3 is fastened to this keeper in the same method as described in Figures 1 and 2.

Figures 23 and 24 show a single locking keeper closely resembling the one of Figures 21 and 22. The only difference is that the latter has the removable block 3 as shown in Figure 9, the former not.

.While certain preferred embodiments of this device have been shown and described, it will be understood that changes of the form, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined by the appended claims.
